The mysterious old time radio series "The Haunting Hour" (actually 30 minute episodes) ran during the mid-1940's on NBC. The names of the cast and production crew were never revealed so when the series stopped airing, it was as if it ceased to exist. The episodes were largely "whodunit" mysteries, with psychological thrills and supernatural themes. With an eerie organ accompaniment and traditional horror vibe, the series represents a mysterious gem from the golden age of radio.
